RF Amplifiers

A RF amplifier (Radio Frequency amplifier) is an electronic device designed to strengthen a signal at a certain frequency range. The RF amplifier enhances the total power of a signal in order to achieve a desired level of noise, distortion or non-linearity. Examples ofRF amplifiers are RF power amplifiers, RF amplifiers with feedback, RF amplifiers with direct coupling and RF amplifiers with voltage regulation.

The RF2335TR7 is a high performance, wideband dual-channel RF amplifier from Skyworks Solutions. It is designed to deliver a gain of 23 dB, with a noise figure of 10 dB, over a wide range of operating frequencies from 2.3GHz to 5.7GHz. It is also capable of providing a single ended power of 20 dBm with a harmonic power of -20 dBc over an input RF power range of -10 dBm to +10 dBm.

Application Field

The RF2335TR7 is ideally suited for a wide range of applications, including cellular infrastructure, satellite communication, radio links, satellites, point-to-point radios, global positioning systems (GPS), cellular backhaul, instrumentation, and aerospace applications. It is also well suited for use in wireless base stations, high speed analog and digital receiver applications, and for any application that requires a wide range of frequency coverage.

Working Principle

The RF2335TR7 achieves its high performance through a combination of innovative circuit topologies and the use of advanced timing and delivery methods to ensure superior signal linearity and power efficiency. At its core, the amplifier requires three stages: input matching, gain, and output matching. The input matching stage provides impedance matching and gain adjustment, while the gain stage determines the amount of amplification. Finally, the output matching stage ensures that the signal is properly delivered with very low distortion.

The RF2335TR7 also features integrated temperature sensing and compensation, which helps to maintain optimal gain flatness and maximum linearity in the presence of thermal variations. This ensures that the amplifier will perform consistently across a wide range of temperatures, providing reliable results.

In addition, the RF2335TR7 utilizes advanced packaging technologies to improve thermal performance, reduce form factor size, and make the amplifier more cost-effective. With its high performance, compact size, and cost-effective design, the RF2335TR7 is an ideal choice for many high-performance RF amplifier applications.
